30 Keysight Infiniium 9000 Series Oscilloscopes User’s Guide
2 Using the Oscilloscope
The waveform display area shows up to eight waveforms areas. Several display
options are available, such as grids, or horizontal and vertical scales.
Ground reference indicators appear for each displayed channel, waveform
memory, or math function waveform. The symbol represents the ground reference
point for each waveform; it moves when you change the vertical offset. You can
also drag this symbol up and down to change the vertical offset for that waveform.

Avoid Overdriving Vertical Input Amplifiers
When zooming on a waveform with the oscilloscope running, be careful to keep the signal
within the screen vertically to avoid overdriving the vertical input amplifiers. Overdriving
causes waveform distortion and erroneous measurement results.
